Dots in Global Data Files are used for dot-pathing instead of preserved in key name

[Dermah]

Describe the bug
If a data file has dots in the file name, the dots describe an object path that the data in the file is available at.

To Reproduce
In an eleventy project:

1. Create a file at _data/sites/11ty.dev.json that just contains:

   {}

2. Create a file at index.liquid that just contains:

   {{sites | log}}

3. Run npx @11ty/eleventy
4. See console output:

   { '11ty': { dev: {} } }

Expected behavior
I don't know if this is actually expected behaviour, but I would have assumed it would output

{ '11ty.dev': {} }

The 11ty docs seem to operate under this assumption, because sites with dots in the filename don't show up on the leaderboard due to the unexpected dot-path behaviour.

Environment:

• OS and Version: macOS 10.15.5
• Eleventy Version: 0.11.0

Additional context

• Leaderboards don't display sites that have dots in the _data filename 11ty-website#639
• Dermah/eleventy@0b88d8d could be turned in to a PR if this is actually a bug.

Yes this is absolutely a bug!

I would love a PR on this although I don’t think Dermah@0b88d8d is quite accurate? folder["sub.folder"] works but fol.der["subfolder"] wouldn’t?

Merged #1912, this will ship with 2.0.0-canary.10.

Thank you @Snapstromegon!
